Description

Busbar sealing device and energy storage all-in-one machine Technical Field The application relates to the technical field of batteries, in particular to a busbar sealing device and an energy storage integrated machine. Background In the current age, along with the continuous progress and vigorous development of society, the intelligent progress in numerous fields such as storage, families and travel is particularly attractive. Mobile consumer electronics have shown an increasing trend from the original smartphones, tablet computers, to today's new energy automobiles, smartwatches, smartphones, etc. In the application of these electronic products, batteries are used as energy output terminals and play a key role in providing stable power supply to the devices. The copper bar structure inside the battery is a key component in the battery system, and the bus bar structure is mainly responsible for connecting each battery cell to form a complete circuit so as to ensure smooth transmission of current. For the energy storage integrated machine, a PCS (energy storage converter, power Conversion System) can control the charging and discharging processes of a storage battery to perform alternating current-direct current conversion, and can directly supply power for an alternating current load under the condition of no power grid. Isolating the PCS and battery compartments is an important part in the design of the energy storage system, and when bus bars pass between the PCS and battery compartments, a corresponding wire sealing structure needs to be designed. In the related art, the busbar is generally not sealed, or is sealed by a wire-through ring, and the sealing structure is not tight enough, so that gaps exist in the structure, a large amount of high-temperature smoke can be generated when the battery is out of control, and corrosive gas and particulate matters possibly exist in the smoke, and if the smoke enters the PCS bin through the gaps, the smoke can corrode or pollute sensitive electronic elements in the PCS, thereby causing equipment faults, even electrical short circuits, even causing more serious accidents such as fire and the like. Disclosure of utility model Accordingly, it is necessary to provide a busbar sealing device and an energy storage integrated machine which stably fix a copper busbar and have high sealing performance.
